Dublin Airport's Terminal 1 (T1) is to undergo a major transformation under plans that have been lodged with Fingal County Council.

The core façade and the roof of the terminal are to be replaced with a new modern, energy efficient structure that will completely transform the external appearance of Terminal 1 and give it a new visual identity.

The existing concrete fins, which are near the end of their life and need to replaced, will make way for a combination of glass and solid panels to create a fresh look for T1 that will improve the overall visual appearance of the airport campus.

The planned works to the façade follow a major upgrade to both the Departures and Arrivals areas of Terminal 1 in recent years. New floors and lighting were installed and both areas were reconfigured to introduce more natural light to the building.

"Terminal 1 has been at the heart of Dublin Airport since 1972 and has welcomed more than 450 million passengers during 48 years of use," said Dublin Airport Managing Director Vincent Harrison.

"These works are part of an overall programme to ensure that T1 can continue to successfully serve Ireland for many decades to come," he added.

"While passenger traffic had been hit by the impact of COVID-19, as custodians of Dublin Airport on behalf of the State, daa must always take a prudent long-term view in relation to managing the facility. As certain elements of T1 are approaching the end of their life, it makes sense to seek planning permission now for these works, which will be carried out over the coming years."

The project to upgrade the façade and other elements of Terminal 1 has been part of the long-term plans for Dublin Airport for several years. As yet, no specific date has been set for these upgrade works to take place.

The northern and southern sides of T1 – effectively the front and the back of the building - will feature significantly more glazing within the new design and the removal of the 1970s concrete fins will create a distinctive new look for the terminal.

As part of the project, planning permission has also been sought to revamp the top two floors of T1, which were originally designed as a multi-storey car park, and are currently used for offices, plant rooms and some staff parking. Remedial works will be undertaken on the concrete spiral ramps adjacent to T1, but they will be retained in their current form.

The changes to T1 will generate a significant improvement in the terminal’s energy efficiency, as it will move the upgraded elements of building from their current BER rating of F to B3. The terminal’s new façade exceeds current energy guidelines by 25%. As part of the planned works, the roof of Terminal 1 will be insulated to the highest standards, thus significantly reducing heat loss from the building.
